报告内容摘要
    Nanomagnetic Technologies have many impacts on biomedical engineering. With a quick and brief introduction on several nanomagnetic technologies being developed in my group, this talk will focus on our previous effort to synthsize the multifunctional magnetic nanoparticles by using a physical gas condensation method [1,2] and our recent effort on the magnetic hyperthermia for cancer therapy and the early detectioin of diseases using thease particles and GMR sensors [3,4,5]. Discover the diseases at early stage is one of key solutions to improve our future healthcare system. Bioassays that detect and quantify biomolecules at ultra-low quantity, with point of care settings, are of great need to enable this. Magnetoelectronics including giant magnetoresistive (GMR) sensor has emerged as one promising platform for biomolecule detection. We herein report the development of a novel detection system based on highly sensitive GMR sensor and sub-13nm high-magnetic-moment FeCo nanoparticles, and the usefulness of this system for quantificating interleukin 6 (IL-6), a potential lung cancer biomarker, with extremely low concentration down to 150 copies per sensor surface. Magnetic label with high magnetic moment is preferred for the sake of generating larger magnetic signal, thereby higher sensitivity for the entire detection system. Furthermore, we successfully demonstrated the feasibility of the nanomagnetic sensing system to directly quantify IL-6 in unprocessed human serum samples and Endoglin in huamn urine samples in 5 min for the first time.
